An advanced persistent threat (APT) is a criminal group which gains access to a network and perform malicious activities. This can result in revenue losses and damage the reputation of an enterprise or government organization. How dangerous is an advanced persistent threat, and what are the best ways to protect your system?
Threat actors use all kinds of hacking techniques to get into a targeted network and stay inside as long as possible. An advanced persistent threat usually targets large organizations and/or government entities. These types of attacks are often orchestrated by hostile nations.
If you consider a regular cyberattack, it doesn’t last long. Hackers want to do their job and get out of a network without being caught. With an APT attack, it’s a whole different story. It can last for months and even years without anyone realizing they have an unwanted guest in their network.
Countries like North Korea, Russia, Iran, and China are known for spying on other nations and collecting intelligence. The Tardigrade malware is one of the recent examples of APT attacks. However, it’s still not clear who might be responsible for orchestrating it.
Deep Panda is a Chinese cyber espionage group that was first spotted in 2011. Two years later, Deep Panda entered the limelight after hacking Adobe and stealing 38 million users’ data, including names, passwords, and payment details. Hackers exploited a known software vulnerability, installed malware on Adobe web servers, and created a backdoor.
A couple of years later, the United States Office of Personnel Management (OPM) became another victim of Deep Panda. Criminals stole 22.1 million records, including the names, social security numbers, and addresses of government employees and their family members.
Researchers claim that cyberattacks against the OPM were conducted in two stages. It’s not known when the first attack happened, but the second one was discovered in 2014.
The Lazarus group is a North Korean state-sponsored hacking organization known for multiple cyberattacks in at least 31 countries. Little is known about this group, but it targets large corporations like Sony, banks, and foreign governments.
During the COVID-19 pandemic, pharmaceutical companies became a common target of the Lazarus group. A wide range of AstraZeneca employees working on coronavirus research received malicious emails, but no data was compromised.
APT34 (also known as Helix Kitten or OilRig) is an Iranian hacker group that has been operating since 2014, primarily in the Middle East.
In 2020, cybersecurity experts discovered that APT34 was targeting Westat, a US-based research company, which provides services to various enterprises and government agencies. Hackers used a phishing email that was masked as an employee satisfaction survey.
Update your software on time. Postponing updates can be tempting, and many employees fall into this habit. Hackers often exploit known software vulnerabilities that have already been patched.
Securely distribute credentials. User credentials shouldn’t be distributed via plain-text emails or instant messaging (where information may be kept in session logs).
Never click on suspicious links. Closely inspect every email you get and never rush into clicking on links or attachments. Phishing emails can be crafted extremely well and cybercriminals use social engineering techniques to make sure you open them.
Train your staff. Cybersecurity awareness is still relatively poor, and many employees lack a proper understanding of digital risks.
Use Threat Protection. By enabling NordVPN’s Threat Protection feature, users can protect themselves against high-risk websites where they might pick up malware and exploit kits. Threat Protection also blocks malicious ads and trackers and scans the files you download to make sure they are not malware in disguise.
